| 摘 要： | 本研究以水芹为材料,通过与传统粗粉碎相对比,研究了超微粉碎时间对水芹粉末的粒度分布、形貌特征、膳食纤维、黄酮及总酚总溶出量、颜色、功能特性以及流动性的影响。进一步针对不同粒度的水芹粉末中主要活性成分的溶出特性,进行测定并对比分析。最后,采用DPPH自由基清除率、羟基自由基清除率、ABTS自由基清除率、总还原力及氧自由基吸收能力(ORAC),评价了水芹粉末的抗氧化活性。结果表明:随着超微粉碎时间的延长,水芹粉末粒径降低至42.19μm,比表面积增加至0.28 m2/g,可溶性膳食纤维溶出量增加至7.26%,黄酮和总酚溶出量显著提高。同时,超微粉碎处理增强了水芹粉的亮度和绿度,改善其溶解性、持水力及膨胀力,但使得水芹超微粉的流动性略微降低。此外,超微粉碎处理极大地提高了黄酮、总酚、可溶性蛋白及多糖的溶出速率,且提高了水芹粉末对DPPH、羟基、ABTS自由基清除能力、总还原力及氧自由基吸收能力。
